To all wkoatit may Beit known that I, Jaooe J. Atnnienioa citizen of the United States, residing at lumbus, in the county of Muscogee and State of Georgia, have invented certainnew' and useful Improvements in Registers; and I 'do hereby declare the. following to be a full, clear, and exact description of the invention,

1 such as will enable others skilled in the art termittent flow of liquid past a certainpoint,

.partly in section.

and has for an objectto provide a meter of this character for application to, a gasolene feeding system wherein the fuel. is fed through, the system by the suction of the internal combustion engine, the present invention -providing a structure of meter which may be actuated by the intermittent suction formed in the system for feeding the fuel.

Another object of this invention is to provide a construction. of register or meter wherein the mechanism is susceptible of operation incident to slight impulse for insuring the correct registering in the meter of all amounts of the fuel which are fed by the vacuum for enabling the correct measurement of the liquid even thoughthe sys-- tem fails to feed the fuel in uniform quantities by the suction in the system.

A further object is to provide an improved clutch for use particularly in the register for insuring the registering of varying amounts of the liquid passing through the system and to take the place of the intermittent grip devices usually employed.

wherein detents and ratchet wheels are used and which require a predetermined movement of the actuating mechanism for efl'ecting a predetermined advancement of the register mechanism.

A further object is to provide in a register an improved arrangement of novel clutches constructed according to this invention for advancing the number of wheels in thedesired directions and retaining them from retrograde movement, and to provide setting mechanisms associated with the clutches in a manner to release certain of the same for admitting the advance or return movement of the setting devices for Specification of Letters Patent.

A sleeve 48 surrounds the arm 42 andFha-saninternal' diameter larger than the external diameterofthe drum for' I vided at one'side 'witha recess 49 into which the lug 455s adapted to fit. When the sleeve 48 turns in one direction it relaxes the spring 44'from the drum 42 and theisleeve "is free to turn in that direction about the drum while leaving the drum stationary. When the sleeve 48 is turned in the other directionit' increases thebihdin action-ofthe spring 44 on th'e'drum 42 an the spring thus cannot'slip about the drum and moves the drum 42 with the sleeve. "As the spring 44 normally grips the drum there can be no slippageof the spring on the drum when the sleeve moves in the direction for coiling the spring, and thus thereis no lost motion in theclutch'; The springs '44 of the clutches on the shafts 38 and 39 are wound in opposite directions and the sleeves-"48 are providcd with radial arms 50 which are of sufficient length to overlap between the shafts. The arms 50 have each a longitudinal slot 51, and the pin 36 mounted on the rod 24 passes through the slots 51 for connecting the arms 50 together and t0 the rod. This structure is shown to advantage in Fig. 10 where it will be observed that when the pin i" opposite directions; Th weclutches for be venieiice of 'idiitification,"are called bn'oneencl withanoutstanding an I,

The inner end ofithe sleeve 52 is provided with anenlarged head or flange fi4 bearingi a inst, the inner sidepf: the bracket 53 anc l carrying an annularrack, 55 adapted to engage the internal racknof the 'adjacent' counter-wheel iO-or 41.; Counter wheels 40 and 4]. areof well known commer- V cial type and the successive wheels of each group areactuated invthe wellknown mannenso that detail illustration is not! necessary, the internal rack present ,in the outer most counter wheel of.each counter up bein utilized'as a convenient means 0 locking t 0 counter wheel to its actuatin sleeve 52 by the-respective rack 55. Any ot or convenient means of connecting the sleeve to 'the outermost wheel of the respective counter group could be used.

'Each sleeve 52 is the driver for its respective counter group and is adapted to rotate its immediately engaged counter wheel in either directionwhen the sleeve is manually actuated, but to move the respective counter wheel only in the predetermined direction of addition or subtraction, as the case may be, when the said sleeve is driven by the shaft which it surrounds. For the purpose of transmitting motion from each shaft to its respective sleeve, the shaft 38 or 39 is intermittently advanced in one direction only (one moving in the opposite direction of rotation from the other) and each is connected with its respective sleeve 52 by a clutch capable of transmitting motion from the shaft to the sleeve during normal operation andcapable of easy and quick release for allowing the sleeve to rotate freely in either direction when the sleeve is actuated manually. The clutches between the shafts and sleeves will, for convenience of identification, be referred to as the intermediate clutches andeach consists of a coiled spring 56 arrangedwithin the respective sleeve 52.

"Eachsleeve 52 has a longitudinal slot 57 fopenin'g through the outer end of the sleeve ,for the reception of a projection or lug 58 formednpon the inner end of spring 56, the

outer e a-er the spring being free and the spring [coiled to fit tightly upon its 'respectiv e s aft, so as to bind upon the shaft wheii thelatter advances in the direchas tending tofurther coil the spring, and ,to releaselits grip upon' the shaft when the shaft moves angularly: in the reverse direc- ',t'io fteiiding'to open the coil. The respective1-sleeve'wouldijthus be held against re- 'verse rotation by the grippingtof the inter- -mediate clutch coil on its sha if provision ';were not made, for temporarily preventing such? action when the sleeve is nioveif manua 1y To this end, each sleeve :52 has; project n' longitudinally from its outerend space ,fin ers 60, there being preferably three such ngers for each sleeve equally spaced about the sleeve. The outer ',or free end of each spring 56 has a laterally extending projection or lug 59, which lies between a pair of adjacent fingers 60, the fingers being sufliciently spaced apart to leave the.projection 59 free so that the outer end of spring'56 is functionally free during normal operations, the relation between adjacent fingers andthe respective projection 59 remaining constant during operation becausethe sleeve and its fingers rotate only the spring 56 rotates, when the parts are actuated by'the inner clutches. That is to say, the longitudinal fingers 60 are spaced apartangularl a distance sufficient to allow free playoft e outstanding lu 59 during the normal operation of a stepy-step forward movement of shaft 39 as the shaft rcceives successive angular impulses from the clutch 44, the spring 56 functioning identically the same as clutch 44 in transmitting step-by-step motion from shaft 39 to sleeve 52. Since the sleeve 52 advances angularly under the impulse imparted by spring 56 in exactly the same ratio as the advance of shaft 39, the relation of the lug or projection 59 to the fingers 60 will remain constant save for the special or extraordinary function in enabling the resetting of the counter group as will be hereinafter set forth, and at all other times than during the operation of such resetting the spring 56 functions as a clutch exactly the same as if the lug 59 were not present, since projection 59 is free to play in the angular space between two of the fingers 60, but, in fact, has in actual practice no perceptible play, because the clutch action both in grasping and in releasing shaft 39 is instantaneous. J

For manually manipulating the sleeves 52, wheels'or disks 61 are mounted on the outer ends of the sleeves, as best seen in Figs. 3 and 5, each wheel 61.havin'g. spaced, relatively narrow prongs 62 projecting in the spaces between the fingers 6Q'ofthe respective sleeve. One prong of each wheel 61 is disposed in positlon for engaging the projection 59 0f the respective spring 56, "So, that when the wheel'fil is turnedintha t direction in which sleeve 52 isnorrnhlly held a aiust rotationby spring 56, the contact 0% the said prong against the pro ection' 59 will cause the spring 56 to be released from its grip on its respective shaftfand the sleeve will thus he left free to rotate-bythe temporary destroyin of the normal function of the intermediate clut'ch spr'mg, the spring revolving freely about its shaft with the sleeve which is; being'actu'ated. 'As soon as the operator releases thewheel 61, the respective spring 56 will again grip its shaft and the parts are restored for continued normal functioning: Obviously, when either wheel 61 is rotated in the direction causing that movementof its respective sleeve 52 which tends to open the'spring 56, there is no resistance to the movement by the spring. and, therefore,each of the sleeves is at all times in condition "for being freely rotated in either direction hyinanipulation of its respective wheel 61, th 'prongs 62 interlocking with the fingers '60:"servingfto insure transmission of motion from the peripheral portion of therespectivewheel to the sleeve.

The shafts 38 and 39 projectoutward from their respective sleeves 52 and receive thereon the drums 63 of outer clutches. The outer clutches have sleeves 64 surrounding the drums 63 with springs 65'between the drums and the sleeves and wound thereon as illustrated in Fig. 8. The sleeves 64 of the outer clutches are preferably formed from a single length of strip material which is wrapped in opposite directions about the spaced drums and extends across the space to connect the sleeves and hold the same against turning. The returned ends of the strip are slightly spaced from the cross bar 66 of the strip to form slots into which project the lugs 67 of the coil springs The springs 65 are so wound about. their drums as to hold the shafts 38 and 39 from retrograde movement. and the clutches thus formed are of the variahlc grip type to operate upon the shafts irrespective of the distance of advance of the shafts. The outer clutches are held in place h v headed screws 68 secured in the outer ends of the shafts 38 and 3 and which engage against plates 69 to hold the same against the outer ends of the drums ()3 for retaining the springs (55 thcroon and inclnsin; the springs.

The shaft 39 imparts motion to a rulmltl' 'dicated by the structure shown in group 72, which counter group may function for any'desired purpose, but ordinarily is intended to serve as a totals counter, while the counter group 11 serves to show the total onl of amp or "other limited use. Similar y to groups 40 and 41, the counter group smade up of counter wheels and mot on tran'smittm devices for imparting motion' from one w eel to the next, all of well known commercial form, so that detail disclosure a'ri'd description is unnecessary. The generaltypeof'these-counter grou sis inp ig. 9, in which the motion *transmitting parts for conveying motion from one wheel to the next" are partly-shown consisting of the boss 76,piIii0n"78" carried thereby, rack 77 with which the pinion cooperates, and recess 79 in the reek cooperating with parts not illustrated. As all of these parts are common to commercial counter groups, a statement of their'ful'iction 'is not required. Any appropriate direct connection may be employed between th shaft 39and the first wheel of counter "group 72, one being shown which possesses the merit of convenience in application and use ofa well known commercial counter wheel. The means'of engagement between the shaft 39 and the first counter wheel of tho' 'group 72 is clearly indicated in Figs.=" 11--'and12, and consists of parts connected with the shaft 39 and adapted to intei lockfwith parts found present in the c'ommercia'lfform of the wheels 72. This connecting means, as shown, consists of the internal-rack and the boss 7 5 of the counter 'Wheel, the boss having a radial slot 74, and

the shaftbeing provided with an eccentric 70 fixed upon the shaft and carrying a disk 71 having'teethedapted to interlockwith the internal gear teeth of the wheel 72. As an additionl connection, a pin 73 is fixed to and outstands from the 'face of disk 71 in position for extending into the slot 74. Thus the shaft 39 is fixed to the adjacent wheel 72 to cause that wheel to rotate with the shaft, but the counter group may easily be withdrawn laterally from engagement with the shaft 39 and with equal ease applied to the shaft when the parts are being disassembled or assembled.

The shaft 38 terminates beyond its inner clutch in a'spindle 80 over which is seated t turn an indicator shaft 81. The shaft 81 carries an indicating drum 82 which is preferahly hollow and substantially semi-cylindrical in construction. The shaft 81 carries an arm 83 (seen in Fig. 9) arranged within the drum 82 and extending through a slot H3 in one side of the drum. The arm H1! is provided with a hook 84 which is re turned through the slot and which carries our 0nd of a spring 85. The other end of the spring is connected to the far side of the drum t for urging the drum to turn in a direction to move the drum against the hoo carries an 'in- 87 with which being carried upon one end of the pin 36 which p through the-outer end of the bar 24. the bar 24 is projected ou'twardl ainst'the stud osition to indicate that suction is not taking place. soon, however, as the bar 24 is drawn inwardly, the arm 88 releases the pin 87 and the spring 85 is free to turn the drum 'sufiiciently for exposingd the signal si e opening 84.

The device may, of course, be modified as to the arrangement of the number wheels to indicate various units of measure according to the application of theregister, and

register 18 operable by connecting the ame gpipe 94 to any source of successive vacuum the im ulses.

his invention is characterized by its capacity for accurate calibration and the use of the coiled spring clutches insures a transof motion to the counters exactly equal arted to the actuated diaphra m under successive vacuum impulses. he term vacuum impulse is employed merely for convenience, signifying, of course, an impulse incident to an unbalanced condition manually actuated of air pressure due to the successive formations of a partial vacuum within the cup 21 caused by the suction of the moving pistons of the engine and their influence upon the vacuum feed system of the engine as is well known in the art. The value of accurate calibration of the present im roved mechanism cannot be over-estimate since lack of accurate calibration would completelyde-* stroy reliability in the operation of the oounto be mentioned to indicate the extreme delicacy with which the present improved instrument must be calibrated, not generally to a whole class of engines or a whole class of vacuum feed devices, but specifically and particularly to the one identical feeddevice on the one identical engine forming part of the automobile to which the present im proved mechanism is clutches thus employed and their coiiperation with the other parts including their relation to the adjusting screw 29 with its capacity for effecting variations inthe actuating strokes of the clutches incident to and corresponding with variations in the feeding system are of prime importance in the commercializing and genera utility of the present invention.
